do 'you' think supernatural can exist?
I consider the concept incoherent. Whatever exists and is causally connected to other existents is another aspect of nature. Why should we partition of a chunk of reality and say that it's not natural just because it's laws and substances might be unfamiliar to us?
Another aspect of the supernatural as commonly described that I find incoherent is that it is a realm outside of time and space that can influence our world but cannot be detected from it. Whatever affects any element of reality does so in time and space, and is detectable through that effect.
What this idea represents to me is a means for saying that what is not detectable is real anyway. To me, reality is the collection of objects and processes that are causally connected in time and space, that is, they can affect one another as cause and effect. A wolf exists because it meets those criteria.
The nonexistent have none of those qualities. They cannot be found anywhere at any time, and cannot modify things that do exist, like werewolves.
Everything real possesses all three qualities, anything imagined possess none of them. The supernatural is a sleight of hand that says that even though this realm is not in time or space, it's still real and can affect reality while being separate from it. Maybe the incoherence of that idea is apparent there now, and why such a construct is logically impossible. Nothing can be causally connected to reality yet undetectable or not existing in time (cause and effect require time for there to be prior and later states as does all action including thought and creative acts).
